DISPLAY APPARATUS.

Specification of Letters Patent.

Patented Jan. 13,1914.

To all whom 'it may concern.'

Be it known that I, JosnrI-I E. Toom a citizen of the Dominion of Canada, and a resident of the city of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Display Apparatus, of which the following is a specification.

My invention has for its primary object the provision of a novel apparatus of the above type, wherein a variety of subjects can be intermittently displayed automati` cally.

A further object resides in the provision of an apparatus by which the actuator is automatically connected and disconnected for successively moving a. plurality of display cards.

Further my invention aims to provide means whereby the actuator and the associated catch device can be reversed in their operation to effect a return movement of the display cards.

With the above and other objects in view, to be referred to as my description progresses, my invention resides in the features of construction, and combinations of parts hereinafter described and succinctly defined in my annexed claims.

Referring to the accompanying drawings, illustrating my invention in such form as now preferred by me: Figure 1 is a longitudinal section of my display apparatus, taken on line 1-1 of Fig. 2. Fig. 2 is a section taken on line 2-2 of Fig. 1 with the display cards removed. Fig. 3 is a fragmentary detail view of the reversible drive mechanism. Fig. 1 is a fragmentary section of the support, and illustrating the cam and its stop mechanism therein, in its two positions of adjustment. Fig. 5 is a plan illustrating more particularly the actuator, and the catch device and controlling cam thereof. Fig. 6 is an edge view of the cam. Fig. 7 is a fragmentary vertical section on large scale, and Fig. 8 is a detail of one of the hinges.

In carrying out my invention I provide a plurality of what I term display cards, the same being of any suitable construction as to be capable of bearing the desired matter to be displayed, and supported for movement, whereby they can be adjusted and thereby be successively exposed.

In my present construction I provide carriers 1, having upper and lower substantially U-shaped holders or seats 2 in which the display cards 3 are preferably removably engaged, said carriers being connected for traveling in arcuate paths, by hinges 5, engaged with common bivots G of a support 4. These carriers 1 are also preferably engaged with curved guides G of the opposite heads 4 of said support, the same being conveniently cut out in their upper and lower edge portions to engage over the said guides G, as clearly shown in Fig. 1.

Reference numeral 7 indicates the actuator and 8 a catch device, the latter having` a follower 8 engaged with a cam 9, which dim controls the operation thereof to swing the carriers 1 successively. Catch device 8 is slidably supported in a guide way 7 of actuator' 7 for projection to and from the path of movement of the carriers 1, which carriers are conveniently provided with engaging parts, in the form of strike lugs, as 1', arranged in spaced relation, whereby they will be successively engaged by said catch device. Actuator' 7 is support-ed for rotary and axial adjustments, the same, as now considered, being fixed to a screw shaft 9a engaged with a nut part 10 of support 4.

Reference numeral 11 indicates a driven shaft rotatably supported in one head 4L and telescopically engaged with shaft 9a, and 12 indicates a hey projecting through shaft 11 into a key way 9 of shaft 9, thereby connecting said shafts for simultaneous movement while permitting Of independent lengthwise adjustment of shaft 9a. Cam 9 is confined between actuator 7 and a fixed collar 13, of shaft 9, in engagement therewith, so that when not held by a stop device 14: to be described, it is held by friction between said parts so as to rotate with the shaft. This stop device 14 is loosely fitted on a depending hub part of cam as shown, and has a finger which projects outwardly between lugs 15 of the cam, to engage one or the other of stop lugs 1 of support 1, this depending on the direction of rotation of shaft 9, and thereby hold the cam against movement in one direction. Said cam, is however, obviously free to move in the reverse direction and therefore, when the direction of rotation of shaft 9a is reversed, by mechanism to be later described, said cam through its frictional engagement with actuator' 7, collar 13 and 'tollower 8 is i'otated until stop device 11i. engages the other stop lug 1. Such an adjustment ot cam 9, as indicated by broken lines in Fig. 4T, obviously reverses the action ot catch device 8, compellingthe same to connect and release the 'iers to swing the latter in the reverse direction or back to their iirst position.

Reference numeral 1G indicates a drive sliatt which may be connected with a motor in any suitable manner, the same being provided with a beveled 'friction wheel 1i' with which similar 'friction wheels 18, 18 forming a part of a reversible driving niechanism, are associated, said friction wheels 1S, 18/ being carried by slidablc sleeve 1), wherel y they can be alternately shifted into engagement with wheel 17. Sleeve 19 connected, by a spline 19', with a shaft Q0 for simultaneous rotary and relative lengthwise movement, such connection enabling power being transmitted through the worm and worm wheel gearing Q1 to shaft 11, while permitting of wheels 1S, 18 being thrown into and out of operative engagement, as hereinbefore set forth.

Reference numeral indicates a shifter arm connected with shaft 9a between collars 22 thereof, and provided on its tree or lower end portion with spaced shoulders or lugs 9,3 between which one arm of a bell crank lever 211- projects to be alternatel7 engaged thereby. Lever 24, which is pivoted, as at Q4', has the other of its arms engaged between shoulders 25 of sleeve 19. A spring Q6 secured to said last named arm bell crank 2Liand to a relatively fixed part on the opposite side of its point of swing, serves to swing the bell crank after its said arm has been advanced by shifter 22 slightly to either side of its central position.

In operation, shaft 92L is rotated carrying with it actuator 7 and catch device S, which latter is projected and retracted by cam 9 to etfect the connection and release between the actuator and carriers 1. During this rotary movement, through the screw threaded engagement with nut part 10, said shaft 9a is also adjusted to shift actuator 7 and its catch device, whereby the latter is presented to engage strike lugs 1 successively. After all of the carriers have been thus moved, gear 18 is shifted into engagement with drive gear 17 through the medium ot shiiter 2Q, bell crank Q11- and spring QG. This 'eitects a reversal in the operation of shaft (la, with a consequent resetting oit cam 9, as to the dotted position in Fig. 4, as hereinbefore described.

Having thus described my invention, what I claim as new and ldesire to secure by Letters Patent ot the United States et rimerica., is:
